järjestelmälohko

Järjestelmälohko, often translated as "system block" or "system unit," refers to the main casing of a computer that houses its core components. This includes the motherboard, central processing unit (CPU), random-access memory (RAM), hard drive or solid-state drive (SSD), power supply, and graphics card. The system block is responsible for processing data, storing information, and enabling the computer to function. It is connected to peripheral devices such as a monitor, keyboard, and mouse, which are typically external to the system block itself. The design and form factor of system blocks can vary significantly, ranging from compact mini-towers to larger full-tower cases, influencing internal component placement and cooling capabilities. The term is most commonly used in personal computer contexts, distinguishing the functional core from the input/output devices.
